What is RAM Mounts?

RAM Mounts is a universal mounting system that lets you secure almost anything almost anywhere. With modular, mix-and-match components, the system offers practical solutions even for demanding mounting challenges.

Applications

Cars, off-road vehicles, trucks, vans, tractors, forklifts, aircraft, helicopters, gliders, ultralights, ATVs, trikes, motorcycles, bicycles, powerboats, sailboats, canoes, kayaks, snowmobiles, specialty vehicles, wheelchairs, fishing, golf, camping, workshops, laboratories, exhibitions, trade shows, presentations and more.

Building a complete RAM Mount

A RAM Mount setup always starts with a base (clamp, base plate, suction cup, or strap clamp). Next comes a connecting arm (available in different lengths) for the appropriate ball size, and finally a device-specific base/holder. Choose a cradle for your device or one of the universal holders.

RAM Mounts ball sizes (diameter)
RAM Mounts system – ball sizes
Approximate load capacity guidelines for aluminum ball sizes (no warranty):
B-size ball
up to approx. 0.90 kg*
C-size ball
up to approx. 1.80 kg*
D-size ball
up to approx. 4.50 kg*
E-size ball
up to approx. 11.30 kg*

* Please note these are approximate values. If your device weight is close to the upper limit of a ball size, we recommend selecting the next larger ball size. The guideline values are provided by the manufacturer (National Products Inc., USA) based on many years of experience across a wide range of applications. This is intended as guidance only; no warranty can be given for the stated values.

RAM Hole Pattern Reference Guide

The RAM Hole Pattern Reference Guide provides a clear overview of common 2-hole, 3-hole and 4-hole patterns, as well as ball sizes (B, C and D) – shown in both imperial (inches) and metric measurements.
